I can see that you asked this question long ago and so you've probably already found the solution, however, I thought I would still answer here in case other users come across it when browsing the forums.
It sounds like what Outside had done, and what you were looking to do, was to disable the A-layer in the plugin. Doing so makes it possible to instantly flip between B-layers with a short upward gesture (*you obviously cannot have any A-layer content in this scenario). With the A-layer still active, you are essentially swiping through a blank page before the next B-layer can appear.
There are many different ways to present materials when combining the various options in the plugin. For more examples, I'd recommend looking through the "Presentation Styles" zip found at the link below:
